Abstract

Procédé pour la préparation de fibres ayant une structure poreuse, fibres poreuse ainsi obtenues et leur utilisation. Ce procédé comprend : la préparation d'une solution ou d'une masse fondue d'une substance naturelle ou polymérisée ; l'incorporation dans la solution ou la masse fondue d'une substance liquide ou solide qui n'est pas miscible avec la solution ou est insoluble dans la solution; le filage du mélange ainsi préparé et l'élimination de la substance non miscible ou insoluble des filaments filés, par des moyens physiques ou chimiques. Utilisation des fibres très poreuses obtenues comme substrats pour des réactifs chimiques, pour l'insolubilisation de protéines et aussi comme tamis moléculaire.Process for the preparation of fibers having a porous structure, the porous fibers thus obtained and their use. This process comprises: preparing a solution or a melt of a natural or polymerized substance; incorporating into the solution or the melt a liquid or solid substance which is not miscible with the solution or is insoluble in the solution; spinning the mixture thus prepared and removing the immiscible or insoluble substance from the spun filaments, by physical or chemical means. Use of the very porous fibers obtained as substrates for chemical reagents, for the insolubilization of proteins and also as molecular sieve.
